Abstract

Electricity supply from PLN network is not always continually available, there could be a blackout at any time. To anticipate such outages, it is necessary to design an automatic transfer switch between the main power source and the backup power. Therefore, it is necessary to develop the automatic transfer switch equipment, where mechanically formed by cam-switch which is driven directly by variable reluctance stepper motor with microcontroller ATMega8535. Automatic mode of operation is determined by stepper motor controlled by microcontroller ATMega8535 while manual mode is done by using grip handle attached to the rotor axis of variable reluctance stepper motor. The determination electricity supply of genset and PLN conditions is determined tolerance of ± 20% from 220 VAC standard voltage of PLN, this condition becomes the basis for moving the stepper variable reluctance motor with the angle-step position -300 for the supply of PLN (I) and +300 angle for generator (II) to move Cam-switch to supply the load. The testing design has done with the following result i.e. the variable reluctance stepper motor will rotate if fullfilled the 20% of tolerance to achieve for the uninterruptible load supply. The transition will take affect within 5 s.Keywords: Automatic transfer switch, Microcontroller ATMega8535, Variable reluctance stepper motor.

Abstract

Battery is an alternative energy source and it is important for energy storage. Battery is often used as energy reserves but the energy in the battery is not able to maintain for longer time. Therefore the battery need to be recharged. This paper proposed a push-pull converter design which is supplied by PLN. In the push-pull converter design the output voltage is constantly in 14.1 volt value with the current of 2.16 ampere. The battery type that being used is sealed lead acid (SLA) which has a capacityof 7.2 Ah with a nominal voltage of 12 volt. The system was designed using MATLAB-Simulink software. The result of simulation shows in three scenarios in example the output of converter when the input fluctuation condition, the load of converter when the input steady state condition, then it connect to battery for charging purpose output of converter already in stable condition.Keywords : Push-pull Converter, Sealed Lead Acid Battery, MATLAB-Simulink

Abstract

Karena menghasilkan emisi gas karbonmonoksida (CO) yang bersifat racun, genset portabel harus diletakkan di luar ruangan dan tidak di dekat pintu, jendela atau ventilasi udara. Kondisi ini menyebabkan posisi genset portabel berjauhan dengan saklar pemindahnya. Oleh karena itu suatu sistem kendali pengasutan dari jarak jauh tanpa kabel diperlukan untuk mempermudah operator dalam mengoperasikan genset portabelnya, sehingga dia tidak perlu berada di dekat genset untuk menyalakan atau memadamkan gensetnya. Dalam penelitian ini telah diupayakan untuk membuat sistem kendali pengasutan genset portabel dari jarak jauh tanpa kabel yang dapat dipasangkan pada genset portabel berbahan bakar premium. Sistem yang dibangun terdiri atas unit pengendali jarak jauh yang berukuran dapat digenggam dan unit aktuator yang secara permanen terhubung secara listrik dengan genset yang dikendalikan. Komunikasi antara unit pengendali jarak jauh dan unit aktuator terjadi secara simpleks menggunakan gelombang radio pita ISM pada frekuensi 433,92 MHz. Sistem yang dibuat telah diimplementasikan untuk menyalakan dan memadamkan genset portabel YMW4500XE merk YAMAWA dan genset tersebut dapat dikendalikan sampai jarak 70 meter dan juga genset yang berada di dalam bangunan berlantai tiga dapat dikendalikan dari dalam dan luar bangunan.

Abstract

The transformer is widely used, both in the field of electricity and electronics. Use of the power system allows choosing the appropriate voltage and economical for each purposes. To obtain a good and satisfying design it is necessary to use computer software in design process. The design of single phase and three phase transformer with the help of computer software is intended to replace the conventional process which is done manually so as to improve the efficiency of time and energy. In this research, we use visual basic 6.0 as a program language and the golden ratio (1 : 1,618) is used as the ratio between the width and thickness of the iron coreKeywords: Transformer, Visual Basic 6.0, Golden Ratio
